thermostat radiator valve not working properly?

Thanks Chris. I've tried with the TVR head off and closed off all the other radiators (just by shutting their TVRs not turning them off at their lockshields). The faulty radiator still is only lukewarm at the top and cold at the bottom. The inlet pipe before the TVR is really hot and the outlet pipe is cold. If I bleed the radiator water comes out and no air at all.

try removing the thermostat head and seeing if the radiator heats. If that does not work try shuting down all the other radiators and see if the rad heats on its own if it does you might have a balancing problem.
